A mobile app I built to solve a daily problem in my student house. Happie helps groups coordinate meals by tracking who's eating, suggesting recipes through a swipe based voting system, and planning special dinners. Built from scratch with full backend infrastructure.
I live in a house with 16 guys in Delft. We cook together, but keeping track of who's eating dinner on any given night became a recurring issue. We'd buy too much or too little food, people wouldn't feel like eating what was made, and coordinating recipes that everyone liked was difficult.
I wanted a simple way to fix this, so I built Happie.
Happie lets users connect in groups and indicate whether they're eating with the group that day. For recipes, I implemented a system similar to Tinder: every day, users swipe through new recipes. The recipe with the most likes gets suggested to the group along with the full recipe instructions.
The app also includes an events system for planning special dinners, so the group can coordinate bigger meals in advance.
Cooking together was only half the chaos. The other half was cleaning up after it, and that turned out to be a different problem: not a scheduling problem but an accounting one. Nobody remembers who left the pan on the stove three weeks ago, so nothing ever follows from it, and the only enforcement left is somebody nagging.
So Corvator is the add on for the part of a shared house that Happie does not touch. It keeps a tally: leave your mess and you get a mark, the first two are free, and every mark after that becomes a penalty chore in a queue. Each Sunday the app pulls four names off that queue and assigns the work. Any large house can use it to divide tasks fairly, whether or not they use Happie.
